Eyup.
When I first had the problem I thought it was a plugged fuel filter, it was missing and stumbling at part throttle, (but oddly, ticking over perfectly.)
So I pulled over and changed it. Ran fine for a short distance then carried on faulting.
Tank sender 6 month old, checked inside tank no evidence of muck or water.
No sedimenter fitted just two nylons lines to the pump.
Checked the gauze on the (near new) delphi lift pump. Clean.
On the mech pump, the timing is controlled by an orifice on the banjo. This is the EDC one... is the timing solenoid controlled? Or is there a fancy return banjo on this too that could be blocked?
Blew out the banjo on return but not convinced it did owt. Very strange contraption looks like a needle or something inside.
I tried running the return into a jar. I am getting a strong flow, 500ml in 30 seconds or less. No bubbles.
Another thought is the pump quantity solenoid (I think) does seem to be buzzing quite loudly. Can't remember if it always did when running though.
Tried it with tank cap loose, don't think it's vacuum in tank.
A bit of a better description of the symptoms:
The tickover is fine, and initial setting off reasonable. On advancing throttle a little more it will start to heisitate and buggerabout. It has put the engine light on once, briefly. As it hesitates and you apply a bit more throttle it will cause the autobox to kick down and then the revs are sort of all over the place as it seems to fight between the autobox and the engine. IF you give it a good bit more throttle, then the 'box kicks down fully and the engine takes off. It then has the usual quite reasonable amount of power and takes off like a scalded cat.
I'm suspecting the TPS. Cleaning the TPS connector and it was fine this morning. However I'm not sure I got it as hot as it was the other night.
